- Further away in every direction we can see galaxies as they were near start of expansion already there then.
Main Question or Discussion Point
Look, I had to digest a lot from answers to first question. Still, I'm missing some main idea. As far as we look in any direction we can see stuff out there from long ago. A grenade explodes in some void. The material travels outward as a sphere of leading faster bits. Slower material follows, and being slower, falls back. Likewise the slowest particles make up a trailing sphere of debris falling further behind.Ahead and behind_nothing. This is an expanding debris-field though not because of anything but relative velocity. Our local universe blew apart, fine. And space expands, fine. The galaxies in opposite ends of the sky were closer before though the space between has grown, but nearly 14 billion years ago they are so far from each other. Wouldn't most of the distance between come from the expansion of space given they started-out in one place.
